| Abstract | Mission-oriented systems are generally designed to perform critical missions under variable operational environments. When it suffers random shocks and additive damage, preventive replacement policies should integrate the damage level, mission reliability, and maintenance costs. However, few of the related works have taken the mission duration into account, which will lead to the overestimation or underestimation of preventive replacement variables. In this study, we propose an optimal replacement policy of a mission-oriented system under additive damage, where a system is replaced preventively at a planned time, at a shock number, or at mission end time, whichever occurs first. Optimal variables are given in analytical and numerical ways to verify the effectiveness of the proposed policies.
